Starting in April, you can immediately sow zinnia seeds in your garden in North Texas. For a second rush of zinnia flowers in the fall, plant seeds in July. Seeds should be spaced in accordance with the instructions on the variety-specific seed packet.
The size of a plant can vary substantially. I space each seed 12 inches apart when planting classic cutting kinds (not compact bedding varieties).
Do zinnias thrive in the heat of Texas?
CAMPUS STATION
A Texas A&M AgriLife Research horticulturist explained that some novel series, such as the marylandica kinds that develop disease-resistant “mounds of color, lasting until frost when planted in late summer, really had the Texas Superstar board members enthused about fall zinnias.
According to Dr. Brent Pemberton, ornamental horticulture for AgriLife Research and president of the Texas Superstar board, Overton, “These are really vibrant plants that we are pushing for usage in the fall. They include all the autumnal hues you enjoy seeing, including oranges, apricots, and yellows.
Horticulturists from Texas A&M AgriLife Extension Service and AgriLife Research conduct extensive tests on Texas Superstar plants around the state. stated Pemberton.
A plant must not only be attractive but also function effectively for customers and growers across Texas in order to be named a Texas Superstar. Superstars must also be simple to grow, he added, guaranteeing that the plants are not only widely distributed throughout Texas but also competitively priced.
Chrysanthemums and fall zinnias can be utilized in a lot of the same situations and have a lot in common, according to Pemberton. But unlike chrysanthemums, which may only bloom for a few weeks and only in chilly weather, fall zinnias can withstand Texas heat well and can continue to bloom until the first frost if they receive adequate water and fertilizer.
He said that technically, the term “marylandica type” refers to the separate species Zinnia marylandica.
According to Pemberton, Marylandica species include the Profusion and Zahara series. They produce lots of flowers and can reach heights of 12 to 18 inches. A single blossom can measure up to 2.5 inches in diameter.
According to him, “mounds of color” alludes to marylandica variants, which are typically bushier or more compact than traditional zinnia variations. Due to their bushy nature, they are perfect for mixed borders, beds, cutting gardens, pots, and “cottage gardens,” a rustic design that combines beautiful and culinary plants.
Marylandica varieties of zinnias are also quite resistant to illnesses like powdery mildew, contrary to normal varieties, according to Pemberton.
According to him, gardeners can pinch off or clip young plants of the traditional types to promote bushiness, but this is not necessary for the more recent varieties. Placing the plants where they receive adequate air movement or circulation will assist them avoid fungal leaf infections as well.
According to him, fall zinnias of all varieties often start appearing in Texas garden centers around September. Typically, they come in 4-inch and bigger pots that can be transplanted into the landscape.

Additionally, you may get them in sizable containers to use as patio plants. They’re enjoyable to use in containers that also contain other fall-themed items, like decorative grasses or ornamental peppers like NuMex Twilight, which was recognized as a Texas Superstar a number of years ago.
According to Pemberton, all zinnia varieties are attractive to a variety of pollinators, including butterflies.
He claimed that they actually blossom more effectively in full sun. They need full sunlight for at least a half-day to thrive, and they do best when planted in well-drained soil or containers with moderate watering.
According to Pemberton, plants can be “deadheaded” (spent blooms removed) to encourage additional flowering and preserve plant attractiveness.
“Dying flowers maintain some color, and deadheading is usually not necessary, although it’s okay to do if you like.
Along with Pemberton, other members of the Texas Superstar board include Drs. Tim Davis and Dan Lineberger from College Station, Drs. David Rodriguez from San Antonio, Drs. Larry Stein from Uvalde, Dr. Cynthia McKenney from Lubbock, Dr. Mike Arnold from College Station, and Dr. Cynthia McKenney from Lubbock.
What month should zinnia seeds be sown?
Light: Full sun is ideal for zinnia growth and flowering. Even in warmer climates with afternoon shadow, they can flower there, but they may be more prone to disease and produce fewer flowers.
Soil: Organically rich, fertile soils with good drainage are ideal for growing zinnias. Because zinnia seedlings are susceptible to rotting in cool, damp soils, having well-drained soil is crucial.
Plant zinnia seeds in rows or clusters spaced a few inches apart. Once the plant has four leaves, thin to 8 to 18 inches apart, depending on the variety.
Planting: Plant zinnias in the spring, just about the time you plant tomatoes, when all threat of frost has passed. Growing zinnias from seeds straight in the garden is simple. Start seeds inside four to six weeks before to your last frost date for earlier flowering.
Can zinnias be grown in Texas?
When I was a child, zinnias were my favorite annuals. My tiny fingers could fit their seeds, and the blossoms of the tall varieties were the size of my hands. Every spring I sowed them among my plants. In College Station, that happened.
When I eventually relocated to Ohio, I was astounded by how much richer their colors were. There were zinnias that resembled jewel-like red, orange, yellow, purple, and white gems. They were unlike anything I had ever seen.
My assistantship at Colorado State, where I began my graduate studies, included taking care of some covert breeding experiments being done on zinnias. There are many different varieties of zinnias, including tall ones with modest flowers and small ones with enormous flowers. Zinnias perhaps covering an acre, tightly encased in nursery shade cloth to keep pollinating insects at bay. I still think that research was the origin of the well-known Peter Pan zinnias, but I was too busy getting engaged and moving back to Ohio to find out.
After finishing graduate school, we went back to Texas, and I immediately started planting zinnias in the spring. I could tell the difference in color intensities. Every summer, we went to see my wife’s parents, which made the disparities even more obvious.
Then it dawned on me. In Texas, zinnias planted for a fall garden would experience lower temperatures more akin to a mild Ohio summer, and sure enough, my fall zinnias displayed the same dazzling rainbow of hues. Better yet, I hardly noticed any of the powdery mildew that frequently covered them in the spring.
Over the years, “Dreamland” zinnias have gained popularity. Their flowers are nonetheless incredibly showy despite being shorter than some of the others.
Ideally, either this week or the following week, your preferred nursery will have very nice 4-inch potted zinnia transplants available for you. Look for healthy plants that have vibrant buds, ideally those that have not yet fully bloomed. After you plant them, they frequently stall out as a result of that.
Plant zinnias in well-prepared garden soil that has been tilled to a depth of 10 or 12 inches, 3 or 4 inches of organic matter, and 1 inch of expanded shale. If you did a good job of preparing the garden for planting this past spring, you can add half as much organic matter while re-tilling.
The projected mature height of your plants can be seen on the plant tags. Taller varieties may withstand some crowding, so space the transplants 40 to 50 percent farther apart than they will be when they are full grown.
Your new plants should be watered right after the soil surrounding them is firmed up. To give my fresh transplants the best possible start, I utilize a water-soluble, high-nitrogen fertilizer that is delivered with a water breaker through a siphoning proportioner. After that, your major objective will be to maintain their moisture at all times and fertilize them every two weeks, once more with a high-nitrogen meal. Texas soils often contain enough phosphorus to encourage healthy flower production. Rarely will more phosphorus be required.
Taller zinnias can be grown successfully in smaller places as well. They will be pleased to assist you if you have a few square feet in the back of a perennial garden, along a walk or road. It all begins this coming weekend.
What plants can survive the heat in Texas?
Pentas are recognized for their star-shaped flowers in a variety of hues, including red, purple, pink, and more. Despite appearing delicate, this plant can withstand the heat. Pentas are warm-climate tropical blooming plants that are native to Africa, Arabia, and Madagascar. Pentas are a terrific choice for luring vital pollinators to your outdoor space and grow nicely in flowerbeds and container gardening.
Which plants thrive in Texas’ climate?
Living in Texas means you should be prepared for extended periods of heat and drought. The absence of regular rainfall is a long-term reality in Texas, despite the fact that many areas of the state have just exited one of the longest, most severe droughts in Texas history.
Homeowners may only be permitted to use the sprinklers once a week during the summer due to watering restrictions that local governments have implemented in order to protect this valuable resource. Sadly, the outcome is frequently brown grass, dead shrubs, and drooping trees. Thank goodness, a wide variety of plant species have adapted to our environment.
Flowers That Survive in the Heat
In the hotter climate, many decorative plants are simply unable to live. Your yard can appear lovely all year long with the help of the appropriate flowers, year after year. Several species of columbine, Coreopsis, Fall aster, Firebush, Plumbago, Rock Rose, several sage varieties, and Shrimp Plant are some of the best options for Texas yards.
Columbine
In the heat of Texas, both red and yellow columbines thrive. These blooms may take partial shade as well as sunny circumstances, but they do best in wet, well-drained soil. When there is a lack of water in the summer, columbines frequently become dormant. Hummingbirds swarm to these blossoms in large numbers. Trim spent foliage from this species in late May to maintain its health and happiness.
Coreopsis
The Lance-leaf Coreopsis grows well in both sun and partial shade and produces yellow, daisy-like blossoms. The species, which draws butterflies, is indigenous to eastern and southeastern Texas. If you remove the spent flowers from the Coreopsis plant, the plant will produce more blossoms.
Fall Aster
This natural shrub can withstand both sun and partial shade and has tiny, beautiful purple flowers. As the name implies, the plant’s flowers are at their greatest in the fall months, and it provides nectar. This plant needs little pruning in the spring and summer to maintain its compact shape.
Firebrush
Hummingbirds are drawn to the plant’s unusual tube-shaped orange-red blossoms. Autumn causes the firebrush to turn crimson, and it has to be sheltered from harsh winter weather. To promote new spring growth, prune this species to six inches after the first hard winter.
Plumbago
This lovely flower has light green foliage and either white or sky blue blossoms. Plumbagos can thrive in partial shade but prefer the morning sun and afternoon shade. If you encounter a strong winter, plumbagos that draw butterflies may need to be pruned back to around six inches.
Rock Rose
This diminutive native shrub, which rarely blooms after the spring, draws butterflies. When left in the shade, the hibiscus-like blossoms of the rock rose are susceptible to mildew. In the late winter, you should prune this blossom down by about a third.
Sage
The cultivars of Cedar, Cherry (or Autumn), Jerusalem, Majestic, Mealy Blue, Mexican Bush, Big Red, Russian, San Luis, and Tropical Sage are incredibly tough and can easily tolerate the Texas heat. They do well in full sun, are resistant to deer and rabbits, and numerous varieties entice hummingbirds to your yard. After the first cold of the year, the majority of species benefit from pruning.
Shrimp Plant
The morning sun and afternoon shade are ideal for this flowering plant. The plant gets its name from the way its blossoms look like shrimp. Shrimp plants thrive when they are pruned back to six inches in the winter to promote new growth and attract hummingbirds as well.
Heat-Tolerant Container Plants
Some people consider flowers, shrubs, and other plants grown in containers around the patio, deck, porch, or garden to be part of the garden’s aesthetic appeal. The finest heat-tolerant container plants are perennials, making it simple to swap between a regular garden plant and a container plant. They also allow you to enjoy the beauty of blooms all year long, no matter the weather. Geraniums, hibiscus, lantana, pentas, and verbena are a few species that thrive in Texas.
Geraniums
These classic blooms thrive in pots, borders, and beds. Geraniums come in a variety of hues and can be planted in large tubs and window boxes alongside other flowers. This plant, which can reach a height of three feet, thrives in summertime mild shade.
Hibiscus
The first image that comes to mind when you imagine a tropical rainforest is of hibiscus blossoms raining from the sky. Hibiscus plants are wonderful focal points for container gardens. If you transfer them indoors during cooler weather, be sure to place them in a greenhouse or bathroom where they can have enough humidity because they do need higher temps to grow. Hibiscus will require support when fully grown, so tie them to a stake in the ground.
Lantana
The lantana makes the ideal companion plant for your outdoor activities with its luscious orange, yellow, pink, or lavender-colored blossoms flooding your containers. Lantanas used to be unruly and unfit for containers, but modern types have learned to control the spindly shoots. In addition to attracting butterflies, lantanas enhance the appeal of these vibrant flowers. Simply watch that the dirt in the container doesn’t totally dry out or you’ll discover your lantanas drooping from dehydration.
Pentas
Pentas have lovely flowers that provide nectar that draws hummingbirds, bees, and other birds. Pentas thrive in well-drained soil and are available in purple, red, pink, and white colors. To encourage flowering, you typically need to pinch back the plant. Pentas thrive under extremely bright light.
Verbena
The warmer climate zones of the United States are home to more than 250 different varieties of this flowering plant. This lovely blooming herb has been around for a very long time, and it does well in direct sunlight. In a hanging basket, verbena is effective and draws butterflies.
Container gardens that can withstand the heat are a great addition to any outdoor living space, but they do require regular watering. When the weather in Texas falls below 45 degrees, they will also need to be brought inside.
Plants That Grow in Hot Weather: What About My Grass and Ground Cover?
The most popular selection for homes is St. Augustine grass. The most common type of grass for lawns, it resembles a lush, green carpet in front of your house. It has several disadvantages, such as being one of Texas’ more difficult-to-maintain grasses. Since it requires more water than most grasses do, by the middle of August your once-beautiful lawn will have turned brown and lifeless.
St. Augustine grass can be effectively replaced by zoysia grass. Although it has a similar lush appearance to St. Augustine, it is more durable and wear-resistant. It benefits greatly from less mowing because it grows slowly. Despite how stunning and resilient it is, it does require fertilization up to once a month and is a little challenging to maintain because it does not repair itself well after being damaged. If you’re unsure about whether Zoysia grass would be a good choice for your lawn, it’s important to speak with a lawn care specialist.
Buffalo grass is the ideal substitute for Zoysia and St. Augustine grass. Its native to Texas and widespread distribution throughout the most arid parts of the state contributes to its more harsh appearance compared to the other grasses. You can skip mowing for a few weeks because it requires less watering and only grows to a height of five to six inches. You won’t need to spend as much effort into making it seem good because it would win “Miss Congeniality” even if it didn’t win any beauty contests.
Rye grass and Bermuda grass are the other two varieties of grass you’ll encounter most frequently in Texas. Like Buffalo grass, they are also heat-tolerant grasses. They are frequently over-sown into lawns with less resilient grasses because of their hardiness to ensure that the lawns stay green throughout the year, no matter the weather.
Plants that grow near to the ground are known as ground cover, and they are perfect for growing around trees, around shrubs, and in place of grass. Depending on how it integrates with the rest of your garden layout, ground cover can either be entirely green or contain low-growing flowering plants.
When applying ground cover in shaded regions, keep in mind that most plants that can withstand heat require some shelter. If there is morning sun or dappled sunlight throughout the day, periwinkle, sweet woodruff, hosta, and creeping thyme are excellent ground covers for your shaded areas.
Plants like phlox are ideal ground cover for sunny regions of your yard because they are highly heat-resistant and function well almost everywhere in your garden.
Heat Tolerant Shrubs
You’ll probably want plants of various heights to define your yard. For Texas lawns and gardens, American beautyberry, Japanese aralia, desert broom, and rosemary are all acceptable options.
American Beautyberry
In the fall and winter, this native plant produces purple berries. The American beautyberry fits well in your understory although deer and other local wildlife may target it. This species often reaches heights and widths of three to five feet without the requirement for pruning.
Japanese Aralia
This enormous plant, which favors complete shade, appears to have been transported directly from the tropics. The Japanese aralia can grow up to 10 feet tall, but under severe winter circumstances, it may die back. The aralia blooms in the fall with tiny cream-colored flowers.
Desert Broom
The desert broom is fairly adaptable, yet it may lose leaves during a drought. The typical height of this evergreen shrub with white flowers is three to six feet. The desert broom is regarded as invasive in some regions of the country due to how rapidly it can spread.
Rosemary
In addition to being a versatile herb, rosemary makes a fantastic heat-resistant shrub for Texas. The herb rosemary spreads widely in your yard and can even act as a groundcover. It has tiny, pale blue blooms that bloom for part of the year. This herb needs good drainage to flourish and draws bees.
Texas Flowering Shrubs That Add Color To Your Yard
Perhaps you want a resilient shrub that also brightens up your yard. Glossy abelia, bottlebrush, and germander are examples of blooming shrubs that do well in Texas and match the bill.
Glossy Abelia
The glossy abelia is a fast-growing, bushy evergreen shrub with fragrant flowers that you might want to include in your landscape. Although the leaves of this plant are fairly sharp, the bush can serve as a place for birds to nest. This plant, which also has pink and white blossoms along with red berries, doesn’t need to be pruned.
Bottlebrush
Bottlebrush plants have striking, spiky-red blossoms that make them stand out. Bottlebrush plants are not only able to endure a Texas summer, but they also have a high level of disease and insect resistance. This shrub with flowers draws bees.
Germander
The light-colored foliage and light-purple flowers of the germander make it stand out. This herb plant, which is related to mint and lavender, can grow in both full and partial shade, as well as in poor and rocky soil. This low-maintenance, deer-resistant plant is simple to prune and will make many areas of your yard more attractive.
Is Xeriscaping Right For Your Yard?
Homeowners have been exploring xeriscaping their yards more frequently in recent years. What does desert landscaping or xeriscaping entail? Most of the time, grass is being replaced by heat-tolerant native plants, ground cover, boulders, paving stones, and other natural components. Mesquite, New Mexico olive, and pinyon pine trees for shade are typical xeriscaping species. You can use climbing vines like wisteria, trumpet vine, and honeysuckle to decorate your yard and draw butterflies, bees, and birds.
